I think the problem was that jstack and jmap didn't work until the debuginfo package was installed. This tells me that the debuginfo stripping in our Linux build system is too aggressive for this purpose.

Yes, https://bugzilla.redhat.com/show_bug.cgi?id=1010786 The distro builds strip too much and remove the needed symtab from libjvm.so.

I think that's something we must fix ourselves. What we really need from OpenJDK is a way to build with complete debuginfo in both binaries and jarfiles.

This was my intent with #2. The jstack/jmap issue needs to be fixed by stripping less debuginfo post-build on libjvm.so.
